her wall with a thickness of 50 m. The second wall had towers and rounded merlons, which surrounded the towers. This outer wall was protected by solid glacis, which is made out of bricks and quicklime. Beyond the outer wall was a water-filled moat.
Golden Gate Palace In the middle of Baghdad, in the central square was the Golden Gate Palace. The Palace was the residence of the caliph and his family. In the central part of the building was a green dome that was 39 m high. Surrounding the palace was an esplanade, a waterside building, in which only the caliph could come riding on horseback. In addition, the palace was near other mansions and officer's residences. Near the Gate of Syria a building served as the home for the guards. It was made of brick and marble. The palace governor lived in the latter part of the building and the commander of the guards in the front. In 813, after the death of caliph Al-Amin the palace was no longer used as the home for the caliph and his family. The roundness points to the fact that it was based on Arabic script. The two designers who were hired by Al-Mansur to plan the city's design were Naubakht, a Zoroastrian who also determined that the date of the foundation of the city would be astrologically auspicious, and Mashallah, a Jew from Khorasan, Iran.
The Abbasids and the round city
The Abbasid Caliphate was based on their being the descendants of the uncle of Muhammad and being part of the Quraysh tribe. They used Shi'a resentment, Khorasanian movement, and appeals to the ambitions and traditions of the newly conquered Persian aristocracy to overthrow the Umayyads. The Abbasids sought to combine the hegemony of the Arabic tribes with the imperial, court, ceremonial, and administrative structures of the Persians. The Abbasids considered themselves the inheritors of two traditions: the Arabian-Islamic (bearers of the mantle of Muhammad) and the Persian (successors to the Sassanid monarchs).
